MACHINE FOR DRESSING RAILS.

To all whom it may concern;

Be it known that we, MICHAEL VVooDs, a subject of the King of GreatBritain and Ireland, and residing at 309 Pigdon street, Princes Hill,Carlton, in the county of Bourke, State of Victoria, Commonwealth ofAustralia, and THOMAS JEFFERSON GLL- BERT, a subject of the King ofGreat Britain and Ireland, and residing at 1 Minnie street, Brunswick,in the county of Bourke, State of Victoria, Commonwealth of Australia,have invented certain new and useful Improvements in and Relating toMachines for Dressing Rails, of which the following is a specification.

This invention relates to machines for dressing rails of the kind inwhich the dress ing means are carried by an attachment which ispivotally secured to the machine as described, for example, in thespecification to our co-pending application Serial No. 538519.

The object of the present invention is to provide an eflicient andreadily attachable combined carriage and holder for grinding meansadapted for use in removing corrugations and to lengthen short jointdepressions.

One mode of carrying out the invention is illustrated by theaccompanying drawings in which- A Figure 1 is an elevation of a combinedcarriage and holder constructed in accordance with the presentinvention. For clearness, parts have been sectioned, omitted or brokenaway. Fig. 2 is a plan of Fig. 1. For clearness parts have beensectioned, omitted or broken away. In this connection, portion of agrinding wheel guard has been removed, portion of one grinding wheelbroken away and part of the worm gear for raising and lowering the saidwheel removed. Fig. 3 is an end elevation of Fig. 2, looking in thedirection of a single arrow. An outer eccentric cylindrical bearing, itstoothed ring and the pinion turning it, at the right hand side, havebeen removed. Fig. i is an end elevation of Fig. 2 looking in thedirection of the pair of arrows. One

grinding wheel and its dresser are removed, and a friction pinion at theopposite side is seen by the omission of an eccentric cylindricalbearing.

In carrying out the invention according to one mode, the combinedcarriage and Specification of Letters Patent.

Application filed February 4, 1911.

holder consisting of a framework a is provided with holes foraccommodating the hollow trunnions on the platform of the raildressingmachine, which holes are covered by removable trunnion caps j, toallow'of the combined carriage and holder being removed when necessary.The framework a is supported on one side by a flanged wheel I) mountedupon a pin 0 which is secured to or formed integral with a slide (Zwhich can be adjusted in a vertical direction by means of a screw 6 uponwhich is a worm wheel f engaging with a worm 9 upon a shaft h which canbe operated by means of a hand-wheel z. The other side of the frameworka is supported upon a series of rollers 79 mounted upon axles Z turningwithin a carrier m which is formed in two parts joined together and isprovided with a hole through which passes the outer end of a pin 01.,the inner end 0 of which is secured to the frame work. The carrier m isprovided with inner and outer lugs p and Q having pins upon which aremounted side rollers r and s, the outer rollers a being beveled so as toclear upstanding fishplates. When grooved rails are to be operated upon,these side rollers are removed.

Mounted behind the rollers are the grinding wheels 6 and at which aredriven, by any suitable motor carried by the rail dressing machine, thearrangement of the gearing for transmitting the drive being as followsThe shaft c, which passes through the hollow trunnions of the machine,is connected at one end to a motor-driven shaft by a suitable coupling,and is provided at its other end with a bevel wheel to engaging with abevel wheel :22 mounted upon a shaft 3/ which carries a toothed wheel 2which engages with a toothed wheel 1 mounted upon a shaft 2. Thesetoothed wheels are interchangeable with reserve wheels carried by themachine, so that a uniform peripheral speed may always be maintained forthe grinding wheels. The shaft 2 carries a frlction wheel 3 engagingwith friction wheelst mounted upon shafts 5 to each of which 1s securedone end of a suitable universal coupling 7 the other end of which isconnected to a grinding wheel shaft 8 rotating within a bearing 9.

In order to start or stop either of the grinding wheels each frictionwheel 4 is mounted eccentrically within a cylindrical hearing 6 to theends of which are secured toothed wheels 10 which engage with toothedpinions 11 mounted upon a shaft 12 which also carries a spiral pinion 13engaging with another spiral pinion 14 upon an;

inclined shaft 15. The shaft 15 carries at its'upper end a vbevel wheel16 engaging;

with a bevel wheel 17 carried on a shaft 18, which can be operated bymeans of a hand wheel 19, which, on being turned, gives a partialrotation to the cylindrical bearing '6 thus moving the shaft 5 carryingthe friction wheel a toward or away from the frict-ion wheel 3. Eachbearing 6 is provided worm 2i engaging with a worm wheel nut 25. Eachwheel 25 rests upon a collar 27 pivoted 1n bearings on the framework andforms a nut around the screw 28 which is pivoted to lugs 29 ofthe'b'earing 9 from the inner end of which extend links 21 pivoted 'tothe framework by means of a pin 30. On

turningthe hand wheel 22 the worm wheel nut 251s caused to ro-tate,'thusraising or lower ng the screw 28 and consequently the grinding wheelshaft.

hen the rails of a track-do not correspond in lateral elevation,that is,when one is higher-than the-other, it is obviousthat independently ofthe position of the machine, the combined carriage and holder, uponreaching such a part of the track, will V turn slightly upon thetrunnion's, thus per- "independently of those in the other rail.

mitting deformities in one rail being treated In order to bring thegrinding wheels into the same lateral plane as the surface of the railwhich is being treated, the flanged wheel 6 is adjusted by means of thehand wheel 2' in the manner hereinbefore described.

Any lateral adjustment of the grinding wheels which may be-required canbe effectedby means of a hand wheel 32 operating a screw 81 whichengages with a screw thread provided in the outer end of the pin n.

' The screw 31 passes through abridge 3 1 and is prevented fronimovi-ngaxially with rela- 'tion thereto by means of collars '33. On turning thehand wheel 82 the combined carriage and holder is moved toward or awayfronithe carrier m,-the lateral play of the wheel Z) on the pin 0permitting of this.

The grinding wheels are provided with a guard 35 secured to theframework and having a hole through its crown above each grinding wheel.Arranged above each hole is a bridge 36 having its legs attachedtotheguard and serving as a guide for a slide 37 connected to a screw 38operated by means of .a hand wheel and nut 39. At the lower end'of theslide 37 is a dresser 4'0 mounted upon a pin 11 carried by the slide, sothat, on turning the hand wheel and nut 39 the dresser 4:0 is depressedinto contact with the grinding wheel.

By using a series of rollers as hereinbefore described and-which formthe subject matter of aseparate application filed by us March 11, 1911and serially numbered 613,790 the grinding wheels are prevented fromfollowing the surface of the rail as the rollers ride upon the tops ofthe corrugations of the rail and thereby permit the grinding wheels towork at a regular depth.
